(Fig. 2i). At one side of the cage is a circular
aperture. Into this fits a section of bamboo, the
end of which within the cage is cut into longitudinal
strips that are made to converge, forming a cone,
through the apex of which the fish can push his
way into the cage, but which prevents his return.

first described above.
A larger trap is the

rivers and also on the

shore into water some
two fathoms in depth.
The free end of the
fence is wound in a
spiral of about two
turns. One or two
gates are made between
the outer and the inner
chambers of the spiral
on the side nearest to
the bank or shore, and
are left open when the trap is set. The fish,
finding themselves confined by the fence, make

do not readily return. The fisherman then closes
the gate and takes out the fish with a landing net.
A prawn trap consists of a cylinder of heavy

bamboo strips like that of the two traps described
above ; the other flattened end is hinged to open
for the extraction of the catch. The trap is baited
